    (54) Graphic decoder circuit


    (57) A graphic decoder circuit for a compact disk player has a color signal generator (6) called a color look-up table (CLUT), which outputs RGB video signals stored in parts addressed by color code signals. The color code signals are simultaneously supplied to a decoder circuit (10), which in turn outputs switching signals (Ys) for superimposition only when specific color signals designated by switching means (11) are inputted. Thus, graphic information from the compact disk player formed by arbitrary colors can be superimposed on pictures obtained from a television receiver or the like.
